Title: Booster circuit
Inventor: SUGASAWA YASUO
IPC: H02M3/07
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To obtain a booster circuit in which short time boost operation is ensured, while reducing power consumption by providing a charge pump circuit with a highest frequency input clock signal at resetting or turning on of power and a lowest frequency input clock signal at low power consumption mode or at a standby. SOLUTION: This booster circuit is for mounting a charge pump circuit 103, a clock frequency setting pointer 101 and a selector 102 for selecting a frequency corresponding to the pointed value. The pointer 101 sets the clock frequency at a highest frequency at resetting or turning on of power, thus boosting the voltage to a desired level in a shortest time. At low power consumption mode or standby, a lowest frequency for sustaining the output voltage of the charge pump circuit 103 at some level or above is set, thus minimizing current consumption. The input clock frequency is set depending on the use conditions during normal operation and the output voltage is kept at a constant level, while minimizing current consumption.
